Hi Ol CS,
I agree completely with your comments, if bisphenol A is reacted into a polymer such as a polycarbonate.
However, it is also used in polymers such as PVC as an antioxidant, where it is free, not reacted in, and can be leached out. I used to work for a company who made plastic additives for PVC, and bisphenol A was a popular additive for food use grades of PVC. It was however used in very low amounts.
Best wishes
